LOGGING-HOOK.

Application filed May 4, 1914. Serial No. 836,250.

To all whom it may concern:

Be it known that I, HENRY HARDISTY, a citizen of the United States, residing at Raymond, in the county of Pacific and State of lVashington, have invented a new and useful Logging-Hook, of which the,

following is a specification.

The invention relates to improvements in logging hooks.

The object, of the present invention is to improve the construction of logging hooks and to provide a simple, inexpensive and efficient logging hook of light strong and durable construction adapted to save time and labor in various logging operations and equipped with means for effectually preventing it from coming accidentally unhooked.

WVith these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described and illustrated in the accompanying drawing and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing-Figure 1 is a perspective view of a logging hook constructed in accordance with this invention and shown locked. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view on the line 33 of Fig. 2. Fig. 1 is a perspective view of the, logging hook, the same. being open.

Like numeralsof reference designate corresponding parts in all the figures of the drawing. I

In the accompanying drawing in which is illustrated the preferred embodiment of the invention 1 designates the body portion of a logging hook consisting substantially of a link provided with one side at a point intermediate its ends with an opening 2 forming inner and outer substantially hooked-shaped terminal portions 8 and 4. The inner hooked-shaped terminal portion of the body 1 is' provided with an eye or opening 5 and is designed to receive a link of a log or other chain (not shown) and the said inner hooked-shaped portion 3 has its end 6 bifurcated for the reception of a re- Specification of Letters Patent.

duced terminal portion 7 of a latch or lap member 8. The reduced end 7 of the latch member. is pivoted in the slot or bifurcation of the end 6 by a transverse rivet 9 or other suitable fastening device and the said latch member which constitutes a latch section is adapted to extend across the opening 2 of the body portion 1 to complete that side of the hook for confining a link or similar member in the closed opening of the logging hook. The latch member is adapted to be swung upwardly or outwardly from the closed position shown in Fig. 1 of the draw-1 ing to the position shown in Fig. 4 to open the logging hook and enable the outer terminal hooked-shaped portion 4 to be engaged with or disengaged from a link. The outer terminal hooked-shaped portion a is adapted to be readily engaged with a link of a chain when the latch member is in its open position.

The outer terminal hooked-shaped portion is provided at the outer side of the opening 2 with a longitudinal extension 10 reduced at the outer side to form a recess 11 for the reception of the overlapping portion 12 of the latch member, and thelatter is reduced at the inner side at 13 to receive the reduced extension '10 of the outer hooked-shaped portion of the body. The extension 10 and the reduced portion 12 of the pivoted latch member have flat faces at their recesses to fit against each other and the said parts are provided with terminal lugs 14 and 15 which fit in-corr'esponding, slots or openings'lfi and 17. When the latch member is closed it is interlocked with the extension 10 against lateral and longitudi- The overlapped reduced nal movement. portions of the body of the logging hook and the latch member have a combined diameter substantially equal to the diameter of the. metal of the outer terminal hooked shaped portion 4, and they are substantially semi-circular in cross-section and are adapt ed to receive a sleeve 18 whichembraces the said reduced portions and retains the same in their interlocked relation whereby the latch member is secured in its closed position and the logging hook effectually prevented from becoming accidentally discon-. nected or unhooked from a logging chain.

The locking sleeve is capable of rotary movement on the reduced overlapped portions 10 and 12 to carry the interior groove 19 into and out of alinement with a longitudinal rib or key 20 formed integrally with I the latch member-and located atthe outer f and permit thesame to be swung to its open l position. When the latch member is closed and it is, desired to lock the same in such rib or key 20.

side thereof as clearly illustrated in Fig. 1 of the drawing. WVhen the groove of the locking sleeve is arranged in alinement with the guide rib or key the sleeve is adapted to slide inwardly or rearwardly' toa point be 7 yond thereduced extension, 10. The portion of the locking member from which the rib or key 20 projects isfround toconform to the configuration ofthe interior of the sleeve. This will release the latch member position the sleeve is moved outwardly along thetlatch member to a point beyond the guiding rib or key 20 and is then rotated to carry the groove out of alinement with the said rib Or /key 20. The outer terminal hooked-shaped portion is provided adjacent to the reduced extension 10 with a project ing. flange 21 arranged in spaced relation T with a guiding rib or key 20 and cooperating with the same to hold the sleeve against longitudinal movement in either direction when the'groove is turnedaway from the The logging hook is simple in its operation and may be quickly engaged with and disengaged from a chain and as the reduced portion of the latch is supported by the extension 10 and the said parts are'embraced advantageously employed wherever a' device 45' of this character is desirable. I

What is claimed is 1., A hook of theclass described comprising a body having an opening at one side and provided at one of its terminals with a reduced extension having a flat outer face, a latch member pivoted at the other terminaljand extending across the said opening andjprovided with a reduced portion having 1 a flat inner face, the flat faces of thetwo reduced parts being in contact when they are overlapped, said latch member being provided adjacent to its pivoted end with a longitudinal rib extending from the pivoted end of the latch member to the reduced por- O'opies of this patent may be obtained for h'tion, and a sleeve arranged on the latch member andvprovided with a groove adapted to receivethe said rib, whereby the sleeve is slidable along the latch member and is' -movable to and from the said reduced portions, said sleeve when arranged on the overlapped reduced parts being located beyond the rib, whereby the sleeve is adapted to be rotatedto carry the groove thereof away from the riband thereby retain the sleeve on the said reduced parts for holding the latch men'iberinv its closed position.

f 2. A hook of the class'described comprising a body provided at one side with] an opening and having-a reduced extension at one side of the opening, saidextension being provided at one end with an outwardly projecting lug and having a transverse slot at its inner end, a latch member pivoted at the other side of'the opening and having a reduced portion" overlapping the said reduced extension, and provided at its inner end with a transverse slot andhaving an inwardly projecting lug at its outer end, the slots of the'said overlapped portion and extension receiving the lugs thereof and'interlocking the said parts at each end of the same, and a sleeve slidable on the "latch member and movableto andfrom the overlapped portionand extension. and adapted to retain the latter in their interlocked relation.

3; A hook of the class described compris ing a body having an opening at one side, and provided at one of its terminals with a reduced extension, alatch member pivoted at the other terminal and extending across the said opening and provided with a reduced portion which is'caused to overlap the said reduced extension, the combined diameter of the reduced portion, and extension being substantially equal to the diameter of the adjacent portion of the body from which the said extension projects, interfitting lugs and slots provided in the reduced extension and'reduced portion to provide an interlocking of'the' parts, a longitudinal rib provided on the. latch member, a sleeve having, a groove to; receive the rib, and a stop provided onthe body adjacent to the reduced extension andspaced from the rib.

"In testimony, that I claim the foregoing V as m'y own, Ihave hereto aflixed-my signature in the presence of two witnesses.
